Claims. (Cl. 12082) This invention relates to a pin pointed weight work holder adapted to hold paper patterns, cloth, leather and other materials on a flat surface against horizontal angular movement with respect to each other on the surface.

It is an object of the invention to provide a weight in the nature of a paper weight which has pin points that will protrude from the under surface of the weight to penetrate the sheet work material when applied thereover and which will prevent this sheet work material from sliding upon the paper sheet and one work sheet overlapping the other against angular relationship upon the horizontal table surface with respect to each other.

It is another object of the invention to provide a pin pointed weight grip wherein the pin points can be automatically retracted upon removing the paper weight and turning the same up side down upon its top side so that these pin points will not be exposed at the time when the weight is not in use and so as to prevent injury of one accidentally intending to grip the weight when it is upside down.

Other objects of the invention are to provide a pin pointed weight holder having the above objects in mind which is of simple construction, inexpensive to manufacture, of pleasing appearance, durable and compact, of convenient size to handle, effective and efficient in use.

For a better understanding of the invention, reference may be had to the following detail description taken in connection with the accompanying drawing, in which Figure 1 is a perspective view of the pin pointed weight work holder applied over two drawing sheets arranged in abutting relationship on a horizontal table surface with the pin points penetrating the paper and thereby positively locking them together against lateral displacement from each other,

Fig. 2 is a bottom perspective view of the pin pointed weight work holder showing the pins protruding from the corners thereof,

Fig. 3 is a fragmentary sectional view taken through the location of one of the pins in the weight and as viewed on line 33 of Fig. 1,

Fig. 4 is a sectional view taken through the pieces of paper being retained by the weight as shown in Fig. 1 and generally on line 44 thereof and at the station of the points of penetration of the pin points through the paper, the paper sheets lying in abutted relationship to one another,

Fig. 5 is a perspective View of a modified form of the invention including the disposition of the weight within a protective cover,

Fig. 6 is a perspective and collective view of the pointed weight assembly shown in Fig. 5 with the parts thereof lifted out of the bottom container,

Fig. 7 is a longitudinal sectional view taken on line 7-7 of Fig. 5, and

Fig. 8 is a similar longitudinal sectional view of the weight inverted to retract the pin points from the bottom of the container.

Referring now particularly to Figs. 1 to 4, 10 represents a weight block formed of heavy material, such as steel or lead of rectangular shape. This block weights any pieces of paper on which the block is placed and which by itself is in the nature of a paper weight. In the corners of the block, openings 11 are drilled therethrough, and supported in these openings are pins 12 having pointed ends 13 that protrude below a flat bottom surface 14 of the block and are retained in the openings by virtue of the tight fit of the pin points with the walls of the openings. The pointed ends 13 are very sharp and the weight of the block is sufficient to cause these pointed ends to automatically penetrate paper, cloth or leather sheet material on which the weight may be placed. If for example, two pieces of paper 15 and 16 are placed on a horizontal surface indicated at 17 in abutting relationship as indicated at 18 in Fig. 4 and the weight disposed between the abutted ends of the paper sheet, the paper will be penetrated by the pin points and these points may even enter the horizontal surface 17 so as to lock the paper to the horizontal surface and relative to each other. The paper sheets will thus be held against lateral displacement upon the horizontal surface.

The paper or other sheet material can be placed on the surface in an overlapped manner and the weight automatically when applied to the overlapped portions of the material serve to hold the sheet materials against displacement of one from the top side of the other. Such a weight is particularly useful when working with paper patterns from which cloth may be cut, flimsy materials, with leather goods such as when laying out ladies handbags and in numerous other industries which require the placing of the patterns on goods on a horizontal table surface.

The openings 11 are very small, less than one thirtysecond of an inch and the pointed ends may be extended any distance from the bottom surface of the block and to a distance of at least one sixty-fourth of an inch so that full penetration of the pin point will be had.

When the weight is taken out of use it can be inverted on its top side 18 and if desired can be used as an ordinary weight when there is no need for the pin points.

Referring now particularly to Figs. 5 to 8, there is shown a modified form of the construction, wherein the pin points are held in a retracted position when the Weight is inverted and rested on its top face. This form of the invention includes a rectangular shape block weight 21 of heavy steel or lead material in which there is disposed at each of the corners thereof a pin 22. Each of these pins have a pointed end 23 longer than the pointed end 13 of the pin of the first form of the invention. This is so that the pointed end of the pin can penetrate and extend through bottom 24 of the container 25 and still provide pin points of such length extending from the bottom 24 of the container. The wall of the container 25 is slightly higher than the height of the block 21 so that upon the container 25 and the block 21-being inverted the block can be lowered onto a cover 26 secured to the open top of the container 25 as shown in Fig. 8. Accordingly, the pin points will not be exposed so that injury to a worker would result. On the top of the block 21 there is fixed a diamond shape plate 23 by means of a screw 29 entering through a countersunk opening 30 in the center of the plate 28 and secured to threaded opening 31 in the top of the block 21. This plate is guided in a diamond shape opening 32 in the cover plate 26 and is accessible to a finger so that the block 21 can be depressed and the pin points extended through the holes in the bottom 24 of the container 25. The pins 22 are secured in a tight fitted manner in small drill openings in the blocks 21.

It should be readily apparent that in the use of this weight this last form of the invention shows the pin points will not be heavily exposed except when the weight is 3 upon the work with the pins extended down and penetrating the work sheets.

It will be further apparent that the pin points are sufficiently sharp and short in length as to, under the weight of the steel block, penetrate automatically the work sheets to be held by the same.

While various changes may be made in the detail construction of the present invention it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.

What is claimed is:

1. A self-penetrating pin pointed work weight holder comprising a block of heavy weight material having a flat bottom surface and a plurality of pins projecting from the bottom surface thereof sufliciently sharp and pointed to penetrate work sheets of paper and the like material under the weight of the block, said pins lying in more than one line on the bottom surface.

2. A self-penetrating pin pointed work weight holder as defined in claim 1, and said block being of a geometric shape having their corners and said pins respectively projecting from the bottom surface at locations adjacent said respective corners.

3. A self-penetrating pin pointed Work weight holder as defined in claim 1 and a container for said block hav- 25 ing a bottom and side walls higher than the block, a cover extending over the container and said pin points being sufficiently long to penetrate the bottom of the container 4 and to extend a suificient distance therebelow so that when the container is placed in an upright manner upon the work sheets the pin points will penetrate the bottom of the container and extend beyond into the work sheets.

4. A self-penetrating pin pointed work weight holder as defined in claim 3, said cover having a central opening therein, said block having a member of the general shape of said opening and adapted to be guided into said opening upon the container being inverted but said member being adapted to be depressed when the work holder is applied to the Work sheets to apply hand pressure to extend the pointed ends thereinto.

5. A self-penetrating pin pointed work weight holder as defined in claim 3, and said block having a threaded hole in the top thereof, a plate member secured to the top of the block by a screw extending through the plate and into the threaded hole, said cover having a guide opening conforming to the shape of said plate whereby said plate may project through the cover when the weight work holder is inverted to retract the pointed ends of the pins.
